WSSC Water tackles PFAS crisis with comprehensive action plan

During a recent government meeting, officials discussed critical updates on the management of PFAS, commonly referred to as \"forever chemicals,\" and the ongoing lead reduction program. Priscilla To, the interim PFAS program manager with WSSC Water, provided an overview of the agency's strategies to address PFAS contamination, which has been a concern since the chemicals were first introduced in the 1940s.

To emphasized that while WSSC Water currently meets safe drinking water standards, proactive measures are necessary to mitigate PFAS levels in the environment. She explained that PFAS are persistent in nature and can be found in various consumer products and industrial applications, making them challenging to eliminate. The agency is focusing on source reduction as the most effective strategy to prevent PFAS from entering the water supply.

Maryland has developed an action plan to minimize exposure to PFAS, which includes significant efforts from 2020 to 2024. However, To highlighted the high costs associated with treatment and the need for cross-border collaboration to effectively manage PFAS, as these chemicals do not adhere to geographical boundaries.

WSSC Water is preparing for upcoming EPA regulations on drinking water, which will take effect in 2029. The agency has been enhancing its internal capabilities, including developing an in-house laboratory to improve analytical measurements of PFAS, which are notoriously difficult to capture at low concentrations. To noted that WSSC Water is involved in multiple research projects aimed at understanding PFAS impacts and treatment methods, with funding exceeding $7 million.

In addition to PFAS management, Jin Shin, the water quality chief manager, presented updates on the lead reduction program. He outlined WSSC Water's historical efforts to eliminate lead pipes from the water system, including a ban on lead pipes in 1954, well ahead of federal regulations. The agency has implemented corrosion control measures that have successfully kept lead levels below EPA action levels.

Shin explained that the focus now is on identifying and replacing lead pipes owned by customers, as the agency has largely eliminated lead pipes from its own infrastructure. He also mentioned recent updates to the lead and copper rule, which will further enhance public health protections.

The discussions underscored the importance of ongoing research, community engagement, and regulatory compliance in ensuring safe drinking water for residents. Both presentations highlighted the need for continued vigilance and innovation in addressing these pressing environmental health issues.
